大麦适时收获是高产丰收的重要环节。该作物的成熟特性及试验研究表明；大麦在蜡熟期收获产量最高，此时籽粒子物质积累最大，完熟期约有变化，完熟以后，麦粒因呼吸消耗及可溶性物质的淋失，干物质含量则有所下降。据我所对大麦不同收获期千粒重变化的测定；）11裸1号乳熟期千 Barley timely harvest is an important part of high yield harvest. The mature characteristics of the crop and experimental studies have shown that: barley harvesting the highest yield in the wax maturity, this time the largest accumulation of seed material, maturity, about the change after maturity, the wheat due to respiratory loss and the loss of soluble material, dry matter The content decreased. According to my determination of different grain weight changes during the harvest of barley;
